Background and activities

The topic of Emil Christiansens PhD is nanoscale characterization of deformed aluminium alloys. It is part of the centre for research based innovation (SFI), partly funded by the Research Counsil of Norway, called Centre for Advanced Structural Analysis (CASA). NTNU, SINTEF and 16 other partners from industy and public sectors participate in the centre.

One of the objectives of Christiansens project is to study how precipitate free zones (PFZs) around grain boundaries in aluminium affect ductile fracture. Experimental data is to be aquired by transmission electron microscopy (TEM), and will provide input to numerical models used and developed in CASA as well as act as a physical verification. TEM is a powerful tool capable of resolving detail on the sub-nanometre level, and in this project TEMs from the TEM Gemini Centre in Trondheim will be used. The TEM Gemini Centre in Trondheim is participating in the NORTEM project, which is a large-scale infrastructure project with the goal of providing state-of-the-art TEM facilities to users in Norway and abroad.
